Syngenta AG (SYT)

Backup Withholding and Information Reporting

Information reporting requirements may apply to a United States holder with respect to distributions by Syngenta, or to the proceeds of a sale or redemption of Syngenta shares or Syngenta ADRs. Backup withholding may apply to these payments if the United States holder fails to furnish its correct taxpayer identification number and certify that such holder is not subject to backup withholding, or to otherwise comply with the applicable requirements of the backup withholding rules. Any amounts withheld under the backup withholding rules generally may be claimed as a credit against such holder’s United States federal income tax liability, and may entitle the holder to a refund, provided that the required information is furnished to the Internal Revenue Service.
